Specification of Letters Patent. Patented June 19,1917.

Application filed January 23, 1917. Serial No. 143,993.

a table to the cutting apparatus, where it iscut into brick forms.

The column is a parallelogram in cross section and its four faces are ofa smooth,

glossy, monotonous sameness, which, become the four edges or smallerfaces of the brick when cut into forms, and thefobject of my inventionis to break up, mat and roughen, in irregular eccentric figures, one ormore faces of said column, with small added ex pense and withoutinterruption of the brickmaking process.

Referring to the accompanying drawings, Figure 1, is a side view of asection of the column of clay and its supporting table, my inventionmounted upon and attached thereto, between the column-forming dies, atthe right and the brick cutting apparatus, at the left (not shown in thedrawing).

Fig. 2 is an end view, showing column in cross-section with rod inhorizontal position, partly buried in the upper face thereof.

Fig. 3-shows a brick, with ornamentation of two of its faces, the resultof the roughing rod action; 10, w, being the relief-like effect and a,00, being the roughened, matted, tangled portion.

Similar letters of reference indicate similar parts throughout theseveral figures, in which I) is the roller or smoother, rotated by thecontinuous forward movement of the clay column, s; e is the frame,provided with bearings for shaft 0, upon which roller 6 is mounted;frame at rear is secured by hinge-shaft f, mounted in bearings providedin top of supporting column g; the lower end of which is secured to thecolumn table base, 7; k is pulley fixed on end of rod m, by which, withbelt to main or line shaft (or gears if preferred) rod m is rotated; g,a support, with lower end secured to table base 7", extends diagonallyupward and backward, is furnished at its outward extremity, withbearings for rod m; a slot is formed at proper point in q for insertionof adjusting bar a; z is weight-frame, showing weightbox it and isadjustably secured by slot in forward end, through which bar 17. passes,held by adjusting nut 0; and fillcrumed on hub of rod m, at Z,- 29 isadjusting nut on bar a, for regulating depth of rod m, penetrating claycolumn face; 8 is the clay column; a shows the outline of brokenup,roughened face of column; t is table top; a, o, o, are rollers uponwhich clay column moves to cutting apparatus; (Z is the outer faceofroller or smoother, b, a, is a weight togive pressure to roller' 6.

Parts designated 0, f, g, 91, Z, p, g, n, are duplicates of similarparts unseen in the drawings.

In operation, the column of plastic clay, s, is forced through thebrick-sizing dies, to-

ward the cutting apparatus-onthe left. The rod, formed of suitablematerial, of proper length to cross the column face and hold pulley andbearings, not less than live eighth inch in diameter, set at right angleto face of column s and contacting with it, is rotated, by belt andpulley k, in reverse direction to the course of the column, at about 4:0revolutions per minute. The rod is set, by means of the adjusting nut p,to bury itself about one thirty second of'an inch into the face of thecolumn it is in contact with.

The frame '5, with its weight it secured by slot on bar a with adjustingnut, 0 and fulcrumed on hub Z, is for regulating pressure of roughingrod m upon clay column surface. The depth to which rod on should enterclay column face is regulated by ad justing nut p, which may raise orlower g, which holds rod m in bearings, as desired. Springs or otherpressure devices may be used instead of weights.

The forward continuous moving column s rotates the pulley 6, its outersurface, d, contacting with ,and smoothing the jagged points of thebroken surface of the column,

and restoring it to its original outline.

The rod m, revolving reversely to the direction of the slower movingcolumn s, wraps about itself the sticky, pasty, plastic material of thecolumn and continuously unloads upon the alreadyroughened, brokensurface, passing forward, leaving it in matted, irregular, eccentric,relief-like and uniquely ornamental figures, ever changing and neverduplicated.

The jagged points are reduced and outline of column restored as itpasses under roller 6, cutting apparatus, where it is cut into brickforms, retaining the ornamental figures produced by the action of therod m. The face of roller may be provided with a textile covering or becordage wound and further ornament the roughened surfaces, by leavingthe imprint thereof on the contacted surfaces.

While only one column surface is shown in drawings and herein described,a horizontal and a vertical rod 722-, may be used at the same time, withproper following rollers or smoothers, which will ornament two facessimultaneously.

Having described my invention, What I claim as new and desire to secureby Letters Patent, is

1. In a machine for producing eccentric irregular figures upon thesmooth face of a column of plastic clay as it moves forward from thedies of a brick-making machine, a round rod of proper dimensions mountedin bearings supported by a suitable frame attached to column table,means for rotating sald rod reversely to the direction of thecontmuously moving column of plastic up said face, a rotating rod,arranged to contact with and across the smooth face of the saidcontinuously forward moving column, said rod being rotated reversely tothe direction of the said moving column, means for regulating thepressure of said rod against said moving column, means for smoothing thelacerated and roughened surface, means for imparting a. textile orcordage-like effect to the raised portions of the relief-like sectionsof the ornamented face, as

specified and set forth.

In testimony that I claim the above, I have hereunto subscribed my namein the presence of two witnesses this 18th day of January, 1917.
